Marine anti-net-twining propeller

Abstract

The invention discloses a marine anti-winding propeller, which includes a propeller, a movable cover ring, a transmission mechanism and an anti-winding device. The transmission mechanism is connected to the propeller through a transmission rod, and the anti-winding device is connected to the movable cover ring through a rod. , the propeller includes blades and a first knife edge, the movable cover ring is provided with a second knife edge, and the second knife edge forms a shearing edge with the first knife edge. When the propeller on the ship is entangled by weeds or fishing nets, the cutting edge formed by the first knife edge on the propeller and the second knife edge on the movable cover ring shreds the weeds or fishing nets; when the first knife edge on the propeller When the knife edge and the second knife edge on the movable cover ring are not sharp, the user can disassemble it and replace it with a new one to be used again; when the movable cover ring on the propeller is not entangled with debris such as weeds or fishing nets , the movable cover ring is away from the blades on the propeller, and the blades can not be restricted by the movable cover ring; when there are weeds or fishing nets and other sundries on the movable cover ring, the movable cover ring surrounds one side of the propeller to ensure The paddles are not affected by it.

Description

technical field [0001] The invention relates to a propeller, in particular to a marine anti-winding propeller. Background technique [0002] With the continuous improvement of science and technology, the ship industry has become more and more developed, and people have higher and higher requirements for ships. The propeller, as a propulsion device that converts the rotational power of the engine into propulsion, is an important component, its performance requirements are particularly stringent. At present, the propellers of boats are all exposed to work. When rotating at high speed, they are easily entangled by weeds or fishing nets in the water. Harm to rare fish in the water. When the ship is driving in the shallows, the propeller is likely to collide with hard materials such as stones at the bottom of the water, causing the propeller to be easily damaged. Therefore, the propellers on the existing ships need to be equipped with protective devices, so that the propellers...
